Late last year some fascinating research revealed that people who take a more deliberative approach to problem solving – rather than just going with their instincts – are also less religious. Now some independent research not only confirms those findings, but also extends them to show how there is a progressive link between thinking style and decreasing religious beliefs.

Gordon Pennycook, at the University of Waterloo in Ontario, Canada, ran the test on 267 people from around the world (mostly North America and the UK) . The basic set up was the same as the previous study.

They gave people a series of three questions, which each had an intuitive, wrong answer. To get the correct answer, you typically need to think around the problem a little.

So, for example, one question asks “A bat and ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost?” The intuitive answer is $0.10, but the correct answer is $0.05.

The key results are shown in the figure. People who believe in a personal god are disproportionately likely to have got every question wrong.

Pantheists, who believe in god as an impersonal force, did better. Deists, who believe in an impersonal god who does not intervene in the universe, did better still, and agnostics even better. Atheists were the most likely to give correct answers.

So deep thinkers, even if they weren’t atheists, were less likely to believe in the conventional idea of a personal god, and more likely to have unconventional religious ideas. Pennycook also showed that deep thinkers were less likely to be involved in religious activities, and that this could be explained largely on the basis of lower belief in a personal god.

They also measured paranormal beliefs, and found that although these were broadly correlated with religious beliefs, many people are believers in either one or the other. Yet paranormal belief was also lower in people who got more questions right.

Both of these effects – on religion and paranormal beliefs – held even after controlling for factors such as age, sex, education and IQ.

In other words, conventional intelligence (problem solving, understanding words) was less important than having a considered, deliberative approach to problem solving.

Now, you may interpret this as evidence that religious ideas are intuitive, but Pennycook disagrees. He suggests that the problem is that many religious ideas are actually counterintuitive. Deep thinkers maybe don’t take these ideas at face value, and so are more likely to dig into the problem and so come to a different conclusion.

One thing I’ve noticed is that “common sense” thinkers also seem to be creationists more than other groups. I’m not sure if that’s the same as “instinctive thinkers”, but it sounds very, very similar.

It’s called common sense because it’s a commonly held belief, not because it’s true.

I would argue that many people seem to think that common sense is true. For example, the guy I’m discussing the Big Bang with. Common sense says that nothing cannot result in the entire universe. But that’s what the best hypotheses that we have suggest.
